SDH04A 1U, STM 4 / STM 1 NG-SDH ADM Rack

The SDH04A is a compact NG-SDH device which supports STM-1/4 ADM and offers various tributary interfaces like E1/T1, V.35, FE/GbE, E3/ T3…etc to provide any service in any slot. The SDH04A is suitable for the applications of GSM/UMTS base station radio access networks (RAN) / MSAN and wireless backhaul. The SFP cage design in SDH04A offers the plug-and-play flexibility to change fibre modules for different bit rate and higher availability to use off-the-shelf fibre modules. The SDH04A is a 1U standard form factor making it easy to fit in any 19” or 23” chassis and outdoor cabinet; Although the SDH04A is a compact NG-SDH box, it also has similar flexibility of shelf-type SDH equipment, such as hot-swappable tributary cards / fibre modules / power modules and 1+1 load-sharing redundant power design. In order to supply reliable networks to carry more upcoming broadband services from wireless / HSDPA base stations to central office, the SDH04A provides carrier-grade Ethernet (E-Line) bundled with L2 functions to totally control QoS between end to end.
